Six cotton cultivars represent the two Egyptian cotton categories, i.e. extra long
staple length (Giza 45, Giza 70 and Giza 86) and long staple (Giza 85, Giza 80 and Giza 83)
were used in this study. It was found that, the whole seed of Giza 70 attained the highest
content for each moisture (7.01%), protein (23.0%) gossypol (0.45%) and Aflatoxins (10.04)
uglkg. Meanwhile, Giza 45 had the highest content of oil (24.5%), and Giza 83 showed the
highest content of ash (5.89%). Giza 86 recorded the lowest content of Aflatoxins (4.73
uglkg) and total fungal count. On the other hand, cotton seed meal of Giza 70 gave the
highest content for each moisture (5.9%), and ash (6%), while the meal of Giza 85 had the
highest content of oil (5.24%).
